## 登陆限制
使用拦截器
在spring-web xml中配置拦截器
~~~
 <mvc:interceptors>
        <mvc:interceptor>
            <mvc:mapping path="/**"/>
            <bean class="com.huangliusong.oa.global.LoginInterceptor">

            </bean>
        </mvc:interceptor>
    </mvc:interceptors>
~~~
编写拦截器
~~~
package com.huangliusong.oa.global;

import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

public class LoginInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) throws Exception {
        //作为登陆限制
        String url=httpServletRequest.getRequestURI();
        System.out.println(url);
        //转换成为小写字母 如果是登陆则直接放行
         if (url.toLowerCase().indexOf("login")>=0){
             return true;
         }

        HttpSession session=httpServletRequest.getSession() ;
         if(session.getAttribute("employee")!=null){
             return true;
         }
         httpServletResponse.sendRedirect("/to_login");
         return false;
    }

    @Override
    public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {

    }

    @Override
    public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception {

    }
}
